To minimize your risk of pregnancy, you must follow Cryselle dosing guidelines carefully. You should take one tablet daily at the same time each day. After finishing one pack, immediately start a new one the next day. When using the contraceptive for the first time, take your first Cryselle dose either on the first day of your period or on the Sunday after your period starts.
Cryselle® (norgestrel/ethinyl estradiol) is a generic version of Lo/Ovral®. There is only one standard dose of Cryselle. As always, do not adjust your dose unless your healthcare provider specifically instructs you to do so. Although this form of birth control is effective when taken as directed, not taking it correctly increases the risk of unintentional pregnancy.
Starting at the beginning of the pack, take one tablet daily at the same time each day. Each pack will last for 28 days (four weeks). After you finish one pack, immediately start a new one the next day. Do not wait any days between packs (this may take a little planning, since you will need a new pack on hand). The first 21 tablets contain the active ingredients, and the last 7 tablets contain no active ingredients. During this last week, your body gets a little break from the hormones, allowing you to have a period. Sometimes, you may have breakthrough bleeding or spotting between periods. If this happens, keep taking Cryselle as usual.
When you take a birth control pill for the first time, you can usually choose to start either on the first day of your period (a day 1 start) or on the first Sunday after your period starts (a Sunday start). Starting on a Sunday may decrease the chance that you will have your periods on the weekends, although this is not always the case. Be aware that if you choose a day 1 start, the labeled days on the pack may not be correct (they are labeled for a Sunday start only). Be sure to follow your healthcare provider's instructions concerning when to start Cryselle.
If you start Cryselle on the first day of your period, you do not need any backup contraception. If you choose a Sunday start, you need to use a backup method of contraception, such as condoms, for a first week. If the first day of your period happens to be on a Sunday, treat this as a day 1 start (no backup needed).
Check with your healthcare provider for more specific instructions if you are starting Cryselle after a birth, miscarriage, or abortion, or if you are switching from a different type of hormonal birth control, such as a different birth control pill, patch, ring, or injection.
